The County Antrim & District Football Association (also known as the North East Ulster Football Association but more commonly as the Co. Antrim FA) is the largest of the four regional football associations within Northern Ireland and affiliated to the Irish FA, the others being the Mid-Ulster FA, the North-West of Ireland FA and the Fermanagh & Western FA.
The Co. Antrim FA held its inaugural meeting on 23 April 1888 at the Commercial Hotel, Donegall Street, Belfast. The founding seven member clubs were Belfast Athletics, Cliftonville, Clarence, Distillery, YMCA, Oldpark and Whiteabbey. These clubs were joined shortly thereafter by Ballyclare, Linfield Athletics, Mountcollyer and Beechmount. In the intervening years the membership has grown from these eleven clubs to in excess of 500. In 1896, the jurisdiction of the Association was extended beyond County Antrim to include all clubs within the Parliamentary boundaries of Belfast, thus including some within County Down.
Aided by a grant from the Irish FA, the Co. Antrim FA set about organising a competition for its members, the County Antrim Senior Challenge Shield, for which the first round draw was made in November 1888. Also organised were a fund raising match, held between Cliftonville and "The Rest", and a first representative fixture, lost 6-2 to a touring side from Canada. In the first few years of its existence Co. Antrim FA XIs also faced teams representing Co. Londonderry, Mid-Ulster and the Irish FA.
